Plot hole: At the end of the movie, snails collect on the apparatus on which Oliver and Oswald have set up a time-lapse camera to photograph their decaying bodies, eventually short-circuiting the camera and wrecking their experiment. As they had previously (01:34:18) set up similar apparatuses in the same area (Alba's country estate) photographing other decaying organisms, why didn't the snails collect on them? (Pleasant film, huh?) (01:52:45 - 01:53:50)

Plot hole: Margaret tells her lover Eric that her husband thinks she's "cruising with Mother." Afterwards, when the villains are closing in for the kill, she tells the others, "It's funny: I told my husband when I left him that I wouldn't see him again" - hardly the sort of thing you tell your spouse after telling him a story to cover up your infidelity.

Plot hole: When Iris Henderson and her two friends arrive at the hotel, Iris orders dinner and asks that it be sent up to "our" room. The waiter arrives when the three are changing. But later, when it's time for bed, Iris says good night to her friends, who leave her alone in the room (as she must be for the sake of subsequent developments).
